Re: Whistle coming from carb area?
It can be a problem with Holleys too. When I said I have had one or two do it, I was talking about Holleys. When the blades are just cracked open, there can be the perfect distance between the wall of the throttle bore and the blade to make a slight sound. Not guaranteeing this is your problem, but I know it can happen. You can also check to see if your plates are aligned. Assuming the transfer slots are cut the same, and I wouldn't be surprised if they weren't on a BG, they "should" (butterflies) hit the transfer slots in the exact same spot on each side. Surprising how many carbs are not hitting each slot in the same place.
